Positive/negative feedback loop scenarios

Positive/negative feedback loop scenarios Questions
State whether each of the following processes are regulated by a positive feedback loop or a negative feedback loop.

A person feels satiated after eating a large meal.____________
The blood has plenty of red blood cells. As a result, erythropoietin, a hormone that stimulates the production of new red blood cells, is no longer released from the kidney.________________________
When bacteria are destroyed by leuckocytes, pyrogens are released into the blood. Pyrogens reset the body’s thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?____________________________________________________________________________________________________________________________________________________________

Positive/negative feedback loop scenarios Task 11 : Essay

Why are negative feedback loops used to control body homeostasis?
An adjustment to a change in the internal or external environment requires a change in the direction of the stimulus. A negative feedback loop accomplishes this, while a positive feedback loop would continue the stimulus and result in harm to the animal.
So what is positive feedback useful for and tell me how it works.
Why is a fever a “good thing” during a bacterial infection?
How is a condition such as diabetes a good example of the failure of a set point in humans?
